Buying hardwood? You won't pay by the "piece"—you pay by the Board Foot. Our calculator helps woodworkers and carpenters estimate volume and cost accurately. A board foot is a volume measurement equal to 144 cubic inches (12" x 12" x 1"). Whether you're buying thick rough-sawn lumber or standard dimensional boards, this tool converts your T x W x L dimensions into the unit that sawmills use.

Project Cost Estimation

Hardwoods like Walnut or Cherry can cost $10+ per board foot! Miscalculating can be an expensive mistake. Enter your cut list dimensions and the price per BF to get an instant total project cost. It's the essential utility for planning furniture builds, ensuring you buy enough material to cover waste without blowing your budget.

Woodworking Fact: Rough lumber is sold by "quarters" of thickness. A "4/4" board is 1 inch thick, "8/4" is 2 inches. This calculator handles any thickness to give you precise volume.
